vo_gpu: ra_gl: fix crash trying to use glBindBufferBase on GL 2.1 

Apparently this is required, but it doesn't check for it. To be fair,
this was tested by creating a compatibility context and pretending it's
GL 2.1. GL_ARB_shader_storage_buffer_object actually requires GL 4.0 or
up, but GL_ARB_uniform_buffer_object requires only GL 2.0.
